PNEUMATICI DISPATCH CARRIERv Filed Oct. C51, 1929 2 Sheets-Sheet4 2 33513 215: s `l( a Patented Aug. 9, 1932 UNITED STATES DANIEL J. MACMILLAN, OF BROOKLYN, NEW' YORK PNEUMAT'IC DISPATCH CARRIER Application filed October 31, 1929.' Serial No. 403,723.

This invention relates to the carriers used for conveying smallr articles such as documents or money, through tubes by forming a current of air through the tubes, sometimes by pressure applied at one end of the tube, and sometimes by exhausting the air at one end of the tube.

The main object of the present invention is to provide a carrier that 4willhave several compartments to contain a plurality of articles.

A further object of the invention is to provide such a structure that will be composed of several inner tubes surrounded by an outer tube, with suitable means for securing these members rigidly together.

Another object is to provide such a device with aV removable liner, in the nature of a tube, that may be a cylinder, or may have an irregular innerY shape toaccommodate articles of flat orm such as bottles.

Another object is, to provide such a structure with means to engage the articles of tubular forni, on the inner end wall of the article,

where the articleis smaller than the containing tube, to prevent the article moving around in the carrier. p p

Fig. llshows asingle carrier.

The arrangement shown comprises ay pair of inner tubes 2 and 3 placed lparallel and adjacent, and an outer tube 4C that surrounds the inner tubes and which engages the outer half portion of the inner tubes and is of a flattened form on two sides. The inner tubes are preterably of rigid material such as fiber or metal; and the outer tube is preferably of a softer material such as leather. A ller piece,

5 and 6, of substantially triangular form, is placed betwen the inner wall of the outer tube on each llat side, and the outer walls of the inner tubes at their adjacent portions, which filler piece may be shaped to entirely fill such spaces. These four members are suitably secured together, as by glue, and screws 7 may be passed through the leather into the filler piece, that may beo wood.

At one end of the carrier it is, closed permanently by suitable means such as a cupshaped member 8 that surrounds the outer member at this end and isfsuitably secured as by rivets 9. A suitable buffer kwall vl0 of felt is secured'to the outer end of this cup member, with elt'washers 11 if desired. The inner end of each inner tube contains a disc 12, 13, of soft material such as telt, to act as .y a cushion for vthe articles.

At the opposite end of the carrier a suitable hinged closure is provided, that may be a piece oi leather 1, with a strap hinge piece 14, and a locking piece 15 on the opposite side to engage the closure and secure it in closed position. ThisV closure will cover the entire end of the outer tube.

Y If desired a separate removable closure may be provided also for each inner tube, as shown a cap`16 with a handle 17 is inserted t0 inthe open end of each inner tube, the handles engaging the closures 13 to hold them in position. t

@ne of lthe particular purposes of the present invention .is to transport the record cylinders otphonographs, that are of a standard size when made, and hence each of the inner tubes Ais provided with'a liningv18 of soft ,material like felt. However, asthese cylinders are used they are shaved and the outer diameter reduces so that it will not snugly fit the inner tube, but could move around and possibly break or become damaged. To avoid this trouble I provide at the inner end if each inner tube, a central boss or plug, 19, of a size to snugly fit the inner wall of these phonograph cylinders 30. At the other end lof the innertube a similar plug is provided;

as shown, a plug 20, of felt or the like is secured on the inner wall of each tube cap 16. um

By this means the records are supported at both ends and when of reduced size and not filling the inner tubes will be rigidly supported at each end.

' Carriers of this character with double tubes, or single carriers such as indicated in Fig. 11, may be provided with a removableY liner tube in the form of a cylinderk 21, that is preferably provided with a soft lining 22 of felt or the like (see Fig. 8). Thesecould' be provided of different thicknessesrof the- 26, 27, 28, 29, and may have suitable filling material at 31V Where it is spaced from the carrier tube. It is to be understood that this inner supporting'tube can be placed in each ofV the two inner tubes 2 and 3 of the double carrier, or can be placed inside yof the single carrier 32 shown in Fig. 11. In either arrangement the boss of soft material may be usedfat the ends to prevent movement of the article. Y

It will be understood that I have .provided a simple andinexpensive structure consisting ofmerely two inner tubes of rigid material,

and an outer tube of leather or the like, easily secured together. The plugs Will prevent certain articles from shaking around. in the tubes. And articlesv of different size can be readily accommodated by the liner tube ot either regular or irregular form.
